Description
This mutation causes pigeons to hatch with very small eyes, or no eyes at all.
Inheritance
Microphthalmia is an autosomal recessive mutation. This means that both parents need to carry the mutant gene for it to express in the next generation. As a recessive mutation, it is possible for microphthalmia to be carried by a bird who does not visually express it.
